Distance control is important along a continuously-moving overhead conveyor to ensure safety and avoid collisions. The VDM54 laser distance measurement sensor monitors and measures the distance between products to keep equal spacing and positioning. VDM laser sensors provide an analog output (4-20mA) proportionate to how close or far an object or reflector is from the sensor, which makes them an ideal solution for most types of measurement and inspection applications, i.e., in the automotive industry. During turns the beam can be switched to the right or the left. This enables the preceding vehicle to be "seen" in a turn.
